Oracle手工不完全恢復（一）：使用當前控制檔案 

示例一：冷備份所有資料檔案--->新建表空間--->備份控制檔案（日誌檔案完好）

 

實驗環境：

當前的控制檔案損壞，新建立的表空間損壞，冷備的資料檔案中沒有該資料檔案的備份，但是控制檔案和聯機日誌中有相關的記錄；由於控制檔案損壞，只能使用備份的控制檔案來做恢復。

  1. --檢視資料庫中已有的表空間
  2. SYS@seiang11g>select * from v$tablespace;

  32. --表空間建立完成之後，備份控制檔案
  33. SYS@seiang11g>alter database backup controlfile to '/u01/app/oracle/oradata/OraDB11g/control.bak';
  34. Database altered.

  36. --檢視資料庫中控制檔案的多元化路徑

  54. --在test4表中插入兩條資料，並提交
  55. SYS@seiang11g>insert into seiang.test4 values(1001,'wjq');
  56. 1 row created.

  64. --執行日誌切換，剛插入的表中的記錄資訊已歸檔

  2. --檢視控制檔案和資料檔案頭所記錄的SCN，發現test01.dbf資料檔案頭沒有記錄

  37. ②    備份的資料備份的SCN比控制檔案SCN還老。

  68. ORA-01110: data file 10: '/u01/app/oracle/oradata/OraDB11g/test01.dbf'

  70. 此錯是因為老備份裡沒有abcd表空間，但只要控制檔案裡記錄了abcd就好辦，方法是建一個datafile的空檔案，而其中內容可由日誌檔案recover(前滾)時填補出來。


  73. --新建一個資料檔案
